T o all whom it may concern Be it known that I, GLEN EsWILSoN, a

- citizen of the United States, residirg"at East Liverpool, in thecounty of Columbiana 5 and State of Ohio, have invented new and useful Improvements in Hose-Couplings, of which the following is a specification.

This invention relates to hose couplings, and particularly to couplings for use in connecting a flexible hose to the nipple or nozzle of a valve structure; and it has for its object the provision of a device of this character which includes mating and cooperating clamping elements which are mounted for swinging movements on the nozzle of the valve structure'and which are associated with a constricting or actuating means whereby when the meansare actuated the companion clamping elements will be made to operatively engage againstV the hose and thereby positively retain the same in connected position upon the nozzle.

With the above and other objects in view, the invention consists of. certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings z-Figure l is a side view of a valve structure, showing the application of the coupling thereto; F ig;

2 is a vertical longitudinal section through the coupling, showing the valve structure in side elevation; Fig. 3 is a section on line 3 3 of Fig. 2; and Fig. 4 isa perspective view of one of the clamping elements.

The valve structure 1 conventionally illustrated herein includes a discharge nozzle 2 having relatively flared external walls 3. In other Words it is described that the nozzle isof increasedexternal diameter toward its outer end. The said nozzle is provided y with fixed brackets or posts 4, which are pivotally connected with lugs 5 of companion clamping elements 6. These elements are of identical formation and each is provided with inner corrugations 7 and outer annular grooves 8, the grooves of one of the elements being alined -with the grooves of the other element for a purpose .to be hereinafter explained. The elements are substantially of semi-circular configuration in transverse secytion and each is of an increased thickness toward its outer end.

An4 actuatingdevicc 9 is preferably conhand-gripping extensions l0, which are connected by an integral arcuate portion 11 and relatively separated and springy arcuate po-rtions 12. The portions 11 and 12 are constructed with' a view to engaging interchangeably and successively in the external grooves of the clamping elements 6. The constricting device is 4designed to slide freely upon both of the elements 6 and when moved in the direction of the outer ends of the elements, the portions l1 and 12, which are yieldable, will be engaged in the external grooves of saidelement 6 and thereby hold the elements in proper confined positions against the adjacent terminal of the hose.

It is evident that the greater the adjustment" of the clampingldevice in the direction of the outer ends of the element 6, the greater the construction of the hose against the nozzle 3 of the valve structure. It is also described that the constricting device'is adapted to be adjusted entirely across the integral post 4 ofthe nozzle 3 and lto rest on one side of the post so as to permit the element 6 to be adjusted to `the dotted line position shown in Fig. 2 of the drawing.r The nozzle 3 is then entirely exposed so as to facilitate the connection of the hose-therewith or the removal-of the same therefrom.

In order thatvthe ho-semay be'freely removed from the nozzle, when desired, I pref-l erably construct the actuating device 9 with such regard to the posts 4 that said device may be moved over said posts and arranged at 011e side thereof as'shown in dotted lines in Fig. 2 and suspended directly, from the inner end of the nozzle 2. This enables one to adjust the gripping elements 6 to the dotted positions shown in Fig. 2, Where they are spaced from each other for a considerable distance relatively and to thereby per-` mit the operator yto freely pass his hand over the nozzle and between said' elements 6 andto electually-grasp the hose and remove the same from said nozzle. f

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion andthe minor details o-f construction may be resorted to Without departing from the'pri'nciple or sacrificing any of the advantages of this invention as claimed.

Having thus describedmy I claim is In a hose clamp, the combination with a member having a nozzle extending therefrom, said nozzle being of a restricted diameter toward its inner end and of circular invention, What configurationin transverse section, and

brackets extending 4laterally from thenozzle adjacent the inner en d thereof, of gripping devices pivoted at their inner,ends to said brackets and movable With relation to said nozzle and s aced from each other along their longitu inal edges, and adjusting means niovably mounted on said devices and having lateral manipulating portions` disposed outwardly of the spaces between said devices,' and adapted to be adjusted over the said brackets and to lie directly at one side thereof and suspended directly from the nozzle beyond the points ofpivotal con- .nection of the grlpping devices 'with said brackets When it is desired to release the devices from the hose.
